The aim of that study investigates the influence the changing climatic condition on 2 different kinds of epoxy coating material film. The first one is epoxy coating film water-borne and the second one is solvent-based epoxy coating film. The fluence will be solved by the accelerated aging through the changing the temperature air and the relative humidity in 30 cycles. During the testing, influence of 2 different kinds of epoxy material measured for tensile strength. The investigation assessed the influence of this accelerated aging on the quality of the finished surfaces. Correlation of liquid properties and rheological properties of finished surfaces. These 2 different kinds of epoxy coating material tested under the 4 different kinds of the temperature cycle

Keywords : Tensile Stress, Coating Films, Epoxy.
